Step‑by‑Step Instructions for Creamy Spinach Mushroom Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Creamy Spinach Mushroom Lasagna cooks evenly and achieves that lovely bubbly, golden top when baking. While the oven heats up, you can start preparing your lasagna noodles.
Step 2: Cook the Noodles
Cook the lasagna noodles according to package instructions until they are al dente, which usually takes about 8-10 minutes. Once done, drain the noodles and set them aside on a clean kitchen towel, ensuring they don’t stick together while you prepare the filling for the lasagna.
Step 3: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced onion and sauté for about 5 minutes until they become translucent. Next, stir in 4 minced garlic cloves and 8 ounces of sliced mushrooms, cooking for an additional 5-7 minutes until the mushrooms are browned and fragrant, releasing their moisture beautifully.
Step 4: Add the Spinach and Season
Once your mushrooms are golden, add 4 cups of fresh spinach to the skillet. Cook until the spinach wilts down, which should take around 2-3 minutes. If you’re using frozen spinach, stir it in now and heat through. Season this mixture with 1 teaspoon each of dried oregano and basil, along with salt, pepper, and optional nutmeg to taste, then remove from heat.
Step 5: Mix the Cheese Filling
In a mixing bowl, combine 2 cups of ricotta cheese, 1 egg, 1 cup of shredded mozzarella, and half of the grated Parmesan cheese. Use a spatula to mix until smooth and creamy, creating the rich filling that will beautifully complement the layers of your Creamy Spinach Mushroom Lasagna.
Step 6: Start Assembling the Lasagna
To assemble your lasagna, spread a thin layer of marinara sauce on the bottom of a 9x13 inch baking dish. This base layer adds moisture and flavor. Next, layer 4 lasagna noodles directly over the sauce, ensuring even coverage.
Step 7: Layer the Filling
On top of the noodles, spread half of the ricotta mixture, followed by half of the spinach and mushroom mixture. Pour a third of the remaining marinara sauce over this layer to keep it moist, and then repeat these layers once more for added depth.
Step 8: Top It Off
Add the last 4 lasagna noodles on top of the final layer. Spread the remaining marinara sauce evenly over the noodles, ensuring no bare spots. Finally, sprinkle the remaining 1 cup of mozzarella cheese and the rest of the Parmesan cheese on top, giving it that irresistible cheesy crust.
Step 9: Bake the Lasagna
Cover the assembled lasagna with aluminum foil, being careful not to touch the cheese, and place it in the preheated oven. Bake for 25 minutes. During this time, the flavors will meld beautifully, and the lasagna will start to heat through.
Step 10: Final Baking
After the initial baking, carefully remove the foil and bake for another 15 minutes. Keep an eye on it; you want the cheese to be bubbling and golden brown, which will indicate that your Creamy Spinach Mushroom Lasagna is ready to enjoy.
Step 11: Cool and Serve
Once baked, take the lasagna out of the oven and let it cool for 10-15 minutes before slicing. This resting period allows the layers to set, making it easier to serve. Get ready to delight your family and friends with this comforting dish!

Expert Tips for Creamy Spinach Mushroom Lasagna
Perfect Noodle Texture: Ensure your lasagna noodles are al dente: Cooking too long can lead to mushy layers, so aim for just firm enough to hold up.
Layering Strategy: Start with a sauce base: This keeps the noodles from sticking and adds flavor. Layer wisely with fillings to prevent a dry top.
Cheese Quality Matters: Use fresh cheese for the richest flavor: Avoid pre-shredded cheeses that often contain additives which can affect melting.
Baking with Foil: Cover during the first baking phase: This traps steam and ensures the noodles cook properly. Remove the foil to create that bubbling, golden cheese crust!
Cooling Time: Don’t skip the cooling step: Allowing your Creamy Spinach Mushroom Lasagna to rest for 10-15 minutes makes slicing easier and the flavors meld beautifully.
